Most comets were formed in the Oort Cloud

The Oort Cloud lies at a distance of between 1000 100,000 times the distance the Sun is from earth.
The region is filled with water vapor and dust particles. Thus, this is what Comets are made of.
Before the earth cooled enough for a crust to form most of the water accumulating in the disk would become rapidly vaporized and blown out into space.
Only after a crust formed was there a chance for the influx of water from sources such as comets to begin to collect in significant amounts.
Recently, a Radio Telescope Array imaged a Protoplanetary Disk

It's like a snapshot looking back at our own Solar System 4.5 Billion Years Ago.
The Gravity of the central star vs the Centrifugal Force, wanting to sling matter outward, causes the matter in an Accretion Disk to 'Stratify' from heaviest to lightest components and you move outward.
